"rtt min/avg/max/mdev = 327.229/377.519/462.590/45.516 ms"

131 bytes = RSS packet size (RACOM data + trace)
10.10.10.242 = repeater IP
192.168.131.243 = destination IP
seq = ping sequence number
rtt = round trip time, the time from transmission to reception

Statistic report:
"5 packet(s) transmitted, 5 received, 0.00% packet loss (0 corrupted), time 4.48 sec"
"rtt: min/avg/max/mdev = 0.371/0.483/0.805/0.166 sec."
corrupted = number of packets which have been received (UDP header is OK) nevertheless
their data have been corrupted (CRC over data is not OK)
time = the total time of ping utility (From Start to Stop buttons)
rtt min/avg/max/mdev = round trip time, minimal/average/maximal/standard deviation
"Load: 1098 bps"
"Throughput: 1098 bps"
Load = the load generated by Ping utility
Throughput = the througput provided by Radio network
"PER: 0.00% round trip, 0.00% one-way"
"BER: 0.00% round trip, 0.00% one-way"
PER - Packet Error Rate, i.e. the probability of a packet being lost. It is calculated for both
the whole round trip and a one-way trip.
BER - Bit Error Rate, the probability of one bit received with incorrect value. Only packets,
no bits can be lost in packet radio network. When a single bit is received wrong, the whole
packet is lost. The BER is calculated from the PER based on this assumption.
"Radio hop with lowest RSS – direction to Destination"
"RSS: 56.0/56.8/58.0/0.7 min/avg/max/mdev"
"DQ : 208.0/219.0/232.0/9.4 min/avg/max/mdev"
"Radio hop with lowest RSS – direction from Destination"
"RSS: 56.0/56.4/57.0/0.5 min/avg/max/mdev"
"DQ : 208.0/216.2/223.0/5.3 min/avg/max/mdev"
There is RSS (Received Signal Strenght) and DQ (Data Quality) information from the radio
hop with lowest RSS, separately for both directions (To and From the destination RipEX).
The mdev values for both the RSS and DQ are provided, giving idea on signal homogeneity.
The lower values are recorded, the more reliable the link should be. The “Homogenity” shows
the jitter of RSS values from individual pings.
